[SC Swamp Fox]

Has anyone ever brought a commercially viable product to market?

I found my own answer, it appears there are lots of waste reprocessing systems around, but I can't see how you could get one to produce more energy then it consumes creating and sustaining the plasma.

[additional reading] I stand fully corrected. Depending on the feedstock, some of these systems are producing more energy then the plasma chamber requires.

I believe there are probably better ways to create biofuels, but after 10 minutes of reading I'm wondering why most large cities aren't building one of these plants to dispose of their municipal waste and generate some electricity.
